Put in service in 1937, this world-renowned bridge, conceived by Joseph Strauss and designed largely by Charles Ellis, was the longest single span (4,200 feet) in the world for a quarter century.

As with many civil engineering projects in their conceptual stages, naysayers scoffed at the Golden Gate Bridge. They said it would be technically unfeasible or too expensive to bridge the Golden Gate, a 1.7-mile-wide opening separating the Pacific Ocean from the San Francisco Bay. They said that the channel was too deep; the tides and winds too strong; the span too long.

Considered one of the world's most scenic mountain drives, the two-lane Going-To-The-Sun Road through Glacier National Park was the first major road to be constructed directly over high mountain terrain, proving that roads did not need to be limited to mountain passes.

Galveston Island is a barrier island located two miles off the Texas coast. The island is about 3 miles wide at its widest and about 28 miles long. The Galveston Seawall extends over 10 miles along Galveston's oceanfront, protecting life and property against hurricanes and tropical storms. 

In 1907, John Fritz, known as the "Father of the Steel Industry in the United States," rejoined the Lehigh University Board of Trustees after an absence of a decade. He began the development of what would prove to be his greatest gift to Lehigh: a modern engineering laboratory and funding for its construction.

The Fresno scraper established the basis for the modern earthmoving scraper, being able to scrape and move a load of soil, then discharge it at a controlled depth. It quadrupled the productivity of manual labor, replacing hand shoveling of earth into horse carts.

"For 273 years, the little stone bridge that carries Frankford Ave. across Pennypack Creek has been doing its humble job with a minimum of attention..."

The Fort Peck Dam was a cornerstone project of the Works Progress Administration of Franklin D. Roosevelt's New Deal. It required the largest construction plant and workforce since the construction of the Panama Canal and peaked at 11,000 workers. It was the largest dam of any type in the world for over 30 years.

"The State [of California] agreed to construct the dam using convict labor for which consideration the State received a grant of land for the construction of a prison and water power rights from the impounded water ...; The work progressed slowly during the dry season by disinterested convict labor using hand tools since the use of machinery was forbidden ...;"

The Fink Deck Truss Bridge is thought to have been originally used on the Norfolk and Western mainline railway. It was moved to its present location and converted to a vehicular bridge over a railroad spur in 1893 when the Norfolk and Western mainline was moved. It was relocated again in 1985 to Lynchburg's Riverside Park to serve as a pedestrian bridge.

In its day, the famous Erie Canal was the world's longest canal and America's greatest engineering feat. It was the principal route for emigrants from the East and agricultural products from the West. Before construction of the canal, New York City was the nation's fifth largest seaport, behind Boston, Baltimore, Philadelphia and New Orleans. Within 15 years of its opening, New York was the busiest port in America, moving tonnages greater than Boston, Baltimore and New Orleans combined.
